Model InstaTrans-XD​​​

Oxygen Transmitter​​​​​​



This model utilizes a design to meet the requirements of NEMA-4(IP-66) levels as well as ATEX Zone 0/1/2 and FM/FMc Class I Div 1 approvals when used with select intrinsic safety barriers. In addition, the CSA approval extends to Class I Div 2 as a non-incentive device without the use of barriers. The transmitter head contains the electronics and user display interface including 4-button design to access functions.


A fully upgraded microprocessor-based platfor​m gives a more compact, single PCB design to simplify maintenance and reduce shelf spares. The new interface allows for a fully settable single range form 0-10 ppm to 0-25%. New advanced functions are also available as standard including 4-20mA output adjustment to optimize single output and cold boot capability as a beneficial troubleshooting tool.
